R&B singer Chris Brown’s reputation as an imbecile (among other things) continues to precede him, and this one has nothing to do with his Frank Ocean fight.

The Atlantic Wire reported Tuesday that the Los Angeles County district attorney just filed a motion against the “Don’t Wake Me Up” singer, alleging that Brown lied about completing his court-mandated community service, which was his entire punishment after he pleaded guilty to assaulting his then-girlfriend, pop diva Rihanna, in 2009.

Brown requested his community service be transferred to Virginia, where he has a residence, but the L.A. DA wants the 23-year-old to complete his community service in Los Angeles and "modify the terms of his probation accordingly,” The Atlantic Wire wrote.

After investigators from the L.A. DA’s office went to Virginia to see how Brown's community service was progressing, the inquiry "revealed no credible, competent or verifiable evidence that Defendant Brown performed his community labor as represented to this court."

No one from the Virginia's Probation and Parole Office "ever approved, scheduled, supervised, monitored, or verified any of the community labor reported," the motion read.

According to TMZ, instead of picking up trash in Virginia, Brown was on a private jet to Cancun.

The news site added that Richmond Police Chief Bryan Norwood told a judge in a Sept. 14 letter that Brown finished 202 days of community service, even though he was ordered to complete only 180.

TMZ says the problem with this letter is that the Richmond police admit Brown was supervised on only nine or 10 occasions.

The D.A. referred to Brown’s documentation as "at best sloppy ... and at worst fraudulent reporting."

Brown’s probation violation dating back to his 2009 Rihanna assault isn’t the only one listed in the motion. TMZ cited his fight with R&B crooner Frank Ocean, who he alleges that he was called a “f**got” by someone and then Brown threatened to shoot him. The fight allegedly all stemmed from quarreling over a parking spot.

Ocean reportedly said in a blog post that he wasn’t going to press charges against Brown, just as Rihanna refused to press charges after the beating he gave her three years ago.

What's more, Brown and Ocean are competing against each other for Best Urban Contemporary Album at the Grammys on Sunday.

According to TMZ, other probabtion violations for Brown include:

--Testing positive for marijuana

--Failing to obtain a travel permit

-- Allegedly grabbing and throwing a fan's phone in Miami

-- Throwing a chair through a window at "Good Morning America"

But Brown’s lawyer, Mark Geragos, told the Associated Press the motion is defamatory and added: "In essence, it calls everyone a liar in the Richmond Police Department and the Virginia Probation Department."

Geragos threatened to seek sanctions from the District Attorney’s Office for filling a "frivolous, scurrilous and frankly defamatory motion."
